Not all MW are Created Equal
To power 500,000 homes reliably, the grid needs...
Wind Solar + Battery
requires ~10x more
capital investment, 9x
more installed
capacity, and ~1,300x
more land than a
modern gas plant to
achieve a similar level of
reliability before
considering
transmission costs
1,000 MW of modern
efficient gas plant
110 acres
or
9,000MW of renewable energy
(Wind + Solar + Battery)
